31st Battery, 9th Brigade April 15th - The enemy’s heavy artillery has been most active. Particular attention was paid to VIMY RIDGE. There was however, a marked absence of shelling by the smaller calibres.O.O. 63 issued to-day gives the new zone boundaries as follows –RIGHT – T.19. central - T.14. Central – N.34.1. 0.0LEFT – S.24.1.7.9 – T.8.Central – T.3.6.4.0The 32nd Battery did not get its last gun into position until noon to-day. The roads were knee deep in mud and jammed with traffic; often there were no roads at all but a series of shell craters. At times the horses belly deep in mud were unable to make any progress except with the aid of several detachments manning wheels and drag ropes. On several stretches of the shell torn road, the guns travelled on their side as often as they did on their wheels but nevertheless the battery arrived in position with no casualties either to personnel or equipment. The 45th Battery moved forward to-night to their advanced position.
